General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| Genentech USA, Inc. | 65 | $55,961 |
| Genentech, Inc. | 19 | $22,830 |
| Novartis | 4 | $9,156 |
| Hikma Pharmaceuticals USA | 1 | $1,500 |
| Ferring Pharmaceuticals Inc. | 1 | $1,260 |

| Sanofi | 1 | $134 |
| Merz North America, Inc. | 1 | $107 |

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
